Author here. I have a Nexus 6. I hadn't tried the Google Play app until today so my observations were based on the sample app that I had built and another Flutter app that's in the play store called Newsvoice. I was under the impression that the Flutter sample app was just a github repo, and I didn't go through the trouble of trying it out.

The Flutter app in the Google Play store does lag for me during the first run of most large animations (nav drawer open/close, shared transitions, etc.). The second time those animations are run, everything is smooth. There must be some sort of caching in place for animations.

As far as I could tell, everything else seemed to be fine. Scrolling performance was good, as were smaller animations like checkboxes and switches.
